Reforming capacitors (technical description, not politics)

[David Gesswein]

When I reformed the 1967? capacitors in MARCH's straight 8 I took some
data showing the improvement in leakage and also measured capacitance and
ESR. I couldn't find original spec for the capacitor but the values
seemed reasonable compared to datasheet for more recent capacitors.
